- Open-source and free, powerful parametric modeling capabilities, extensive Python API for automation and customization, multi-platform (Windows, Mac, Linux), active community, constantly evolving with new features.
- Steeper learning curve than some commercial CAD software, UI can be complex for beginners and sometimes inconsistent between workbenches, some workbenches are more mature and stable than others, performance can be an issue for very large assemblies.
最适合：
- Designers, engineers, hobbyists, and architects looking for a free and open-source parametric 3D CAD modeler with extensive customization and automation capabilities through Python scripting.
